Yes, A little over a year ago I dynoed the motor at KRE and it made 558 HP at the crank. At the time of the dyno I was using 1.65 rockers, now I have 1.5's on there. The reason for the change was because the 1.65's were giving .594 lift on the exhaust and after I did some checking I found that the retainer was hitting the seals at about .590. So, I went back to the 1.5's. The reason I don't have as much clearance is because I had KRE install valves I already had and I think they are .100 in shorter than what they install. Only have about 6 runs at the 1/8 mile track and I havn't been able to get it to hook. Best so far is a 7.97 @91.44 MPH with a 2.05 60ft at a race weight of 3850 lbs. Hopefully I will get a chance to go to Beech Bend Raceway and get some 1/4 mile times soon.
Larry, no I am not using a spacer but I do use one of those 1/4" thick gaskets. Also, I didn't get a chance to run the car with the WFO installed.
